Plenty of players have accused FortressCraft, a Xbox Live indie title, of being a “clone” of the popular PC digging-and-building title Minecraft.

But Minecraft developer Mojang couldn’t care much less.

“As long as they’re not using anything we made, we don’t care,” Mojang’s business chief, Daniel Kaplan, told Eurogamer. “Like, would the Doom creators sue everybody who has done an FPS? Don’t think so.”

Meanwhile, FortressCraft, created by Adam Sawkins, has already earned $1 million since its release on the XBLIG platform in September. Sawkins has rejected the comparisons of FortressCraft to Minecraft, as Eurogamer reports.

‘The Notch Defense Force said things like ‘you even stole the name’, but the actual gameplay is nothing like Minecraft,’ Sawkins said at the time.

“‘Minecraft has been squeezed out of its own market,’ he said on the subject of Minecraft’s XBLA release. ‘It might do well on the name alone, but if you want sexy graphics and shaders and the creative aspect, you have FortressCraft. If you want to fight monsters and share stuff with your friends, you have Total Miner. Nobody will pay for Minecraft when they can pay $3.00 for Total Miner or FortressCraft.’

Either way, Mojang doesn’t seem too upset by what some might call imitators (and others, competitors). With the release of Minecraft on Xbox Live forthcoming, plus the big success of more than 700,000 downloads of Minecraft – Pocket Edition on Android and iOS (at $7 a pop), it’s seems Mojang and Minecraft are doing just fine.
